Chemistry Project : Extraction of zinc from zinc blende
Aug 31, 2012· zinc sulfide undergoes froth floatation, a process to separate materials based on whether it is hydrolilic or hydrophobic, to obtain an ore concentration. Note that at this point of time, only 50% of the ore concentration is zinc. Next, Roasting of the ore concentration will then convert the zinc sulfide into zinc oxide and sulfur dioxide.

The ore has first to be separated from clays and other silicates ('gangue') after which the lead ore and the zinc ore are separated. The process used is froth flotation, a succession of stages each delivering a greater concentration of the lead ore. The ore, containing gangue (which typically contains 38% lead) is ground with water to a particle size similar to that of fine sand (< mm).
